How To Block Calendar from getting indexed

[nakodari]

Ok folks I have an important question. Google is indexing my Forum's Calendar like crazy but I want to disable it by mentioning it in Robots.txt file. The forum name is http://www.office2010club.com/

I want to disable calendar from getting indexed because I find no value in it being indexed. Quick replies would be most welcomed.

You can disable the calendar for guests and/or add this line to your robots.txt

Disallow: calendar.php
